Freemium Push Starter: Recapture Anonymous Cart Abandoners

Are you losing customers you never even knew you had? A huge number of online shoppers add items to their cart but leave before ever entering an email address. They become ghosts in your analytics—high-intent visitors who vanish without a trace. Traditional email reminders can't reach them, and without contact info, retargeting is impossible. This silent exodus of anonymous abandoners represents a significant, untapped revenue stream.


The Freemium Push Starter Playbook offers a powerful, cost-free solution. By integrating OneSignal's push notification service, you can prompt visitors to opt-in for browser notifications with a single click—no email required. When an opted-in user abandons their cart, an automated push notification is sent directly to their device, reminding them of the items they left behind. This playbook provides the fastest and cheapest way to build a direct communication channel with anonymous shoppers, allowing you to validate the impact of push-based cart recovery without any initial software investment.

Expected Outcomes

  • Recover a percentage of sales from anonymous users that would otherwise be permanently lost.
  • Build a new, owned marketing channel of push notification subscribers for future campaigns.
  • Gain a direct line of communication to your most engaged, yet anonymous, website visitors.
  • Validate the effectiveness of cart abandonment push notifications for your specific audience with zero initial software cost.

Integration Logic

  • Cart-Sync Push Trigger

    This integration is triggered by a webhook from an e-commerce platform when a user's cart is updated and subsequently abandoned (typically defined by a period of inactivity). The webhook payload, containing the user's external ID, cart details (items, value), and other metadata, is received by the integration platform. The platform then formats this data and makes a POST request to the OneSignal API's 'Create notification' endpoint. It uses the user's external ID to target the specific user and populates a pre-defined OneSignal template with dynamic content from the cart data, such as the number of items or the name of a specific product. The result is a personalized, timely push notification sent directly to the user's device, encouraging them to complete their purchase.
